WRENCH.

SPECIFICATION forming part of Letters Patent N o. 681,260, dated August27, 1 901. Application filed April 22, 1901. Serial No. 56,904. (N111001610 To all whom, it may concern,.-

Be it known that I, OLIVER E. PONTIO Us, a citizen ofthe United States,residing at Wauseon, in the county of Fulton and State of Ohio, haveinvented new and useful Improvements in lWrenches, of which thefollowing is aspecification This invention relates to wrenches; and theconvenient form of quick-acting wrench by j desired distancealong thehandle or stock of .l the implement, so as to bring said movable jawinto close relation to a nut, pipe, or other article to be grasped andheld between the wrench;jaws, after which the movable jaw may beadjusted into actual contact with or close relation to such nut orarticle and its movement away from the same prevented during theOperation of turning a nut or other j articleV The specific object-ofthe invention is to L l I" provide, in connection with the movable jawadjusting-screw and movable jaw and which also embracesthe handle of thewrench and Alies in position to be conveniently grasped and feed oradjusting screw, a forked thumbpiece which forms a connection betweenthe and operated by the thumb and forenger of the operators hand.

With the above and other objects in view the invention consists in thenovel const-rucg E tion, combination, and arrangement of parts claimed.In the accompanying drawings, Figure 1 is hereinafter fully described,illustrated, and

` a side elevation of a wrench constructed in j responding parts in allfigures of the drawings. l

Referring to the drawings, 1 designates the handle or stock of thewrench, which is shown as of rectangular shape in cross-section andprovided at one end with a fixed or immovable jaw 2.

In carrying out the present invention a i `movable or adjustable jaw 3,which embraces by means of a pivot-pin 7.

the handle 1 and is slidingly mounted thereon for movement toward andaway from the fixed jaw, has pivotally connected thereto a forkedthumb-piece 4, which is provided with a lug or ear 5, which fits in asocket 6 in the movable jaw 3 and is held pivotally therein Thethumb-piece isis provided with fork-arms 8, which extend transversely ofthe handle 1 and on opposite sides thereof, said fork-arms serving toguide the thumb-piece as it is vibrated toward or y away from the handleand also forming iinger-grips, so that the operator may grasp saidfork-arms between his thumb and forefinger for the purpose ofdisengaging the feed or adjusting screw in order to slide the movablejaw quickly along the wrench-handle. The forked thumb-piece is furtherprovided with a recess 9, in which is received one end of the adjustingor feed screw 10, the threads of which are adapted to engage teeth orthreads 11 in the rear edge of the handle 1, as clearly illustrated inFigs. 1 and 2. The screw 10 is rotatably mounted on a pin 11,

. Which is screwed into a threaded Opening in the forked thumb-piece 4and held. The pin 11a may, however, be fastened to the forkedthumb-piece in any preferred way. When the thumb-piece is rocked outwardor away from the handle 1, the adjusting-screw 10, which is carried bythe thumb-piece, is also rocked outward and moved out of engagement withthe teeth or threads 11 on the handle. The screw 10 is normally held inengagement with the handle by means of a pressure-spring 12, one end ofwhich is connected to the movable jaw 3 and the opposite or free end ofwhich bears against the forked thumbpiece 4. v

It will be seen that the operator by graspv ing the forked thumb-piece lmay rock the adjusting or feed screw 10 out of engagement with thehandle 1 and then quickly slide the movable jaw toward or away from thefixed jaw, so as to bring both jaws into close relationship to the nutor other object to be clamped. The spring then restores theadjusting-screw to its normal position, after which the operator byturning said screw may eifect a nice adjustment of the parts prior toturning the nut on or off. Y

IOO

Having thnsvdescribed the invention, what I claim as new, and desire tosecure by Letters Patent, is-

A wrench comprising a, handle; a fixed jaw 5 thereon; a movable jawslidingly mounted thereon; a spring-pressed thumb-piece pivotallyconnected to the sliding jaw and provided with fork-arms which embracethe wrench-handle; and an adjustngscrew car- Ared by the forkedthumb-piece amd having 1o a'swivel engagement therewith and a threadedengagement with the handle ofthe Wrench. In testimony whereof I affix mysignature in presenee of two Witnesses.
